Introduction

The aim of this use case is to determine the population uptake metrics for SARS-CoV-2 testing, SARS-CoV-2 vaccination, and hospitalisation due to an infection with SARS-CoV-2 in the adult population who have been tested at least once for COVID-19 and/or have been vaccinated.
Testing statistics, vaccination uptake and coverage, and hospitalisation will be assessed by age, sex, geographical region, target groups, and socioeconomic indicators.

The purpose of this use case is not only to answer the research questions but also to test the feasibility of conducting such a study without the EHDS infrastructure in place and then with the different services that will be developed by the HealthData@EU pilot project. These findings will factually present the benefits and added value of the HealthData@EU infrastructure.

Research Questions

Four research questions has been established to conduct this use case:

1. What is the average number of PCR tests within the study period in the cohort by socioeconomic levels?
2. What is the average number of positive COVID-19 tests per individual in the cohort by socioeconomic levels?
3. What is the ratio between individuals who received a complete vaccination scheme against SARS-CoV-2 compared to the total number of individuals in the cohort at the end of the study period?
4. What is the ratio of individuals who have been hospitalized at least once due to COVID-19 compared to all individuals in the cohort since January 1, 2021?
5. What is the ratio of individuals who received a complete vaccination scheme against SARS-CoV-2 and have been hospitalized at least once due to COVID-19 compared to all individuals fully vaccinated in the cohort since January 1, 2021?

Data analysis is divided into three sections, each focusing on specific research questions:

  • Testing metrics (RQ 1 & 2)
  • Vaccination Metrics (RQ3)
  • Hospitalisation Metrics (RQ4-5)

Cohort Information

The study population consists of all residents of a country tested and/or vaccinated with at least one dose of any SARS-CoV-2 vaccine. People who are below 18 years old, not a resident of the participant country and people who have not had a documented confirmed SARS-CoV-2 testing after January 1, 2021 (SARS-CoV-2 vaccine roll-out), are excluded from the analysis.

Cohort size: 61500 unique individuals.
Study period: from 2021-01-01 to 2022-12-31.
Age range: 18-115.
Threshold: groups with less then 10 individuals are excluded.
Groups excluded: 3037 groups*.

*Excluded groups are represented by the value “Excluded” under the group size (N) in data tables.
